To all whom it may concern:

Be it known that l, Louis B. l-lAnvnY, a citizen of the United States, residing at Sacramento, county of Sacramento, State of California, have invented certain new and useful improvements in Demountable Hub Structures; and it do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in demountable hubs for vehicle wheels, and is a divisional part of the application for, patent on disc wheel, Serial No. 340,904, filed November 26th, 1919.

Theprincipal object of the present inven-' tion is to provide a demountable hub structure particularly intended to be used in connection with the sta' dard wheebhubs of l ord cars.

Another object of the invention is to provide a hub structure of the above stated type which may be applied and connected to either the front or rear standard hubs of the car, without necessitating any changes being made to either thehord hubs or to my improved hub structure. 7

As a further object 1 have provided a structure which may be easily and quickly applied or mounted, and as easily removed.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efl'ective for the purposes for which it is designed.

'lhese objects it accomplish by means of arrangement of parts as will fully appear by a perusal of the following speciflcapion and claims.

in the drawings simi ar characters-of reference indicate corresponding parts in the several views. 7

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes a hub of the type provided on Ford cars, which has a flange 2 at its inner end, rovided with a plurality of bolt holes 3. s ordinarily constructed and equipped, the wooden wheel is slip ed over the hub and held in place against t e flange 2 by means of bolts through the flange 2, there being an outer flange corresponding to the flange 2 through'which the bolts pass.

. at that end, so

cinching up of 1 no. aaoaea nividea an application the Serial No. rat os. I

When equipping a car with my improved hubs this outer flange, and the original wooden wheel are discarded, a steel disc wheel 1 of the type shown in the copending application No. 340,904 being preferably used instead.

My improvedhub structure comprises a bushing- 5 adapted to be pressed over the hub 1, and to fit snugly against the flange 2, said bushing tapering outwardly toward said flange on-its outer surface as at ti, and beipg radially split for its entire length as at Adapted to be wedged onto the bushing is the actual demountable hub 8, which as outwardly dprojecting and spaced annular flanges 9 a j acent its outer and inner ends, to which the discs o of the wheel aresecured any suitable manner, as by capscrews 9*. v

The vbore of the hub 8 is tapered as at 8 for a necessary portion of its length to conform to the degree of taper of the bushing. The outer end of the bushing projects beyond the bushing as, at 10, and is open as to allow for theproje'ction of the hub 1 therefrom, the standard rear Bil hub being of a different length than the front hub.

The bore of the portion 10 is greater than that'of the hub 1 and the bushing 5 at. that end, except at the outer end of said portion, where an inwardly projecting annularflange 10" is formed which has a neat lit with the hub 1.

1 The hub 8 is pressed firmly onto the bushing and held in such position byboltsf 11 which pass through both flanges 9 and the holes 3 in the flange 2. a I

Outwardly of the flange 2 the-bolts are shouldered as at 12, these shoulders being adapted to abut against the flange 2 when the hub has been drawn as tight as possible onto the bushing, 7

By reason of the bushing being split. the the bolts causes the bushing to bind on the hub 1, and the hub 8 being likewise firmly bound on the bushing by reason of the contacting ta er faces, the majority if not all of the driving strain is taken directly by the bushing and hub 8 rather than by the bolts 11, the latter serving more to prevent loosening up of the parts and the strain thereon is therefore tensional rather than shearing, rendering the use of a few and relatively small bo1ts'practicable.

The bushing being split also allows the latter to accommodate itself to the axle hub, regardlesscf the exact diameter of the latter, which cannot always be depended on as being constant.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims;

Having thus described my invention, What I claim as new and useful and desire to secure by Letters Patent, is:"

1.A demountable hub structure including a wheel-hub member adapted to be removably mounted over the fixed hub of the vehicle, bolts connecting the wheel-hub to ;the fixed hub structure to hbld' the former against lateral' displacement, and means whereby the turning strain of the axle-hub will be taken directly y the wheel-hub rather than by the bolts.

2. A demountable hub structure including a. wheel-hub member adapted to be removably mounted over the fixed hub of the vehicle, bolts connecting the wheel hub to the fixed ,hub structure to hold the former against lateral displacement, and a split taper-bushing over the fixed hub and onto which the wheel-hub is adapted to be forced with the tightening u 3 of the bolts.

3. A demounta'ble hub structure for a fixed hub having an outwardly projectinp flange on its inner end, corn rising a taperbushing adapted to be fitted over the fixed hub, a wheel-hub having a taper-bore to fit the bushing adapted to be driven thereover, and means between the wheel hub and flange to hold the wheel hub and bushing in driving engagement and prevent relative lateral movement of the wheel-hub on the fixed hub.

4. A demountable hub structure for a fixed hub having an outwardly projecting flange on its inner end, comprising a taperbushing adapted to be fitted'over the fixed hub; a Wheel-hub having a taper-bore to fit the bushing adapted to be driven thereover. a flange on the wheel hub parallel to the fixed-hub flange, and bolts through said flanges.

' In testimony whereof I afiix my signature.
